Although most of the FUD is dying down there are still people out there who like to talk against cryptocurrencies and blockchain, one of these prominent FUDsters being the Economist Nouriel Roubini who saw the economic crash of 2008 come from many directions before it happened but at the recent senate hearing was very against cryptocurrencies calling it "the mother of all scams". There are still people like that around, these of course are reduced time after time again and will be long forgotten but their words can affect people who may be on the verge of not being sure of what they have gotten themselves into and if they should trust it or not.
